A colorless, nonvolatile solid, XeO3, explosive when dry: in solution it is called xenic acid.
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
The mass of one molecule of a nonionic substance in atomic mass units.
Band Theory of Metals
Theory that accounts for the bonding and properties of metallic solids.
Refers to the occurrence of an element in an uncombined or free state in nature.
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
Alkaline Earth Metals
Group IIA metals
Free Energy, Gibbs Free Energy
The thermodynamic state function of a system that indicates the amount of energy available for the system to do useful work at constant T and P.
Complex species that contain ammonia molecules bonded to metal ions.
Hydrocarbons that contain double or triple carbon-carbon bonds.
A substance that conducts electricity poorly in a dilute aqueous solution.
A series of reactions (and accompanying enthalpy changes) which, when summed, represents the hypothetical one-step reaction by which elements in their standard states are converted into crystals of ionic compounds (and the accompanying enthalpy changes.)
Standard Molar Enthalphy of Formation
The amount of heat absorbed in the formation of one mole of a substance in a specified state from its elements in their standard states.
Solution in which no more solute will dissolve.
Effect by which all acids stronger than the acid that is characteristic of the solvent react with solvent to produce that acid, similar statement applies to bases. The strongest acid (base) that can exist in a given solvent is the acid (base) characteristic of the solvent.
A physical state of matter which exists at extremely high temperatures in which all molecules are dissociated and most atoms are ionized.
Either the oxidation part or the reduction part of a redox reaction.
A mixture that does not have uniform composition and properties throughout.
A plant extract that has a distinctive odour or flavour.
A substance capable of causing or producing cancer in mammals.
Hess' Law of Heat Summation
The enthalpy change for a reaction is the same whether it occurs in one step or a series of steps.
